Oligopeptide transport permease C-like, N-terminal domain (IPR025966)

Short name: OppC_N

Overlapping homologous superfamilies


Domain relationships



Oligopeptide permeases (Opp) have been identified in numerous Gram-negative and -positive bacteria. These transport systems belong to the superfamily of highly conserved ATP-binding cassette transporters. Typically, Opp importers comprise a complex of five proteins. The oligopeptide-binding protein OppA is responsible for the capture of peptides from the external medium. Two integral highly hydrophobic membrane spanning proteins, OppB and OppC, form a channel through the membrane used for peptide translocation. This N-terminal domain appears to be the first TM domain of the molecule [PMID: 1738314].
